[Nathan Chancellor via Phabricator via llvm-commits]

I too saw issues with this patch with PGO (I was in the middle of writing up a reproducer). My symptom was that stage 3 `check-llvm` would not pass, whereas stage 2 would. This version of the patch on top of 7277d2e1c86bf4d75321efc1195d88ade4bedfa1 <https://reviews.llvm.org/rG7277d2e1c86bf4d75321efc1195d88ade4bedfa1> does not have that same issue.
